Now fixed. Because not only last Friday's dow close was wrong but the one from the previous week was also (slightly) room, I've recalculated everyones scores based on their predictions, so some people's direction may have changed, but this is the fairest way to do it. I've also fixed the problem with the data feed, that hasn't been working ever since we upgraded the database server last week, and partially the friday before (hence the friday close being wrong). Will keep an eye on it tomorrow just to ensure its running smoothly again.
